RPG is a vague and broad term for this and the OP already acknowledged that since English isn't his native tongue. Role playing games used to be done on table tops with pencil and paper and before that it was something psychiatrists did to help with patients and what couples did in the bedroom.
There is a minority that enjoys Civ for it's narrative aspects and I agree that it is largely a strategy game first and anything else second but try not to take RPG to mean a more current definition as it applies to video games. I do see narratives in each of my games but it isnt because i put them there. Any game with a beginning and an end has a narrative and each game I play tells a tale of history because the game is a strategy path through history, even as a number cruncher. It might not be the most interesting narrative (more like a boring history book) but it's still a narrative.
Thanks for saying what I'd have had to say

I'd like to remind all of you, that you dont know if the people who (would) want to play Civ in a more narrative or simulation style are a minority. All you know is that it seems like fewer of these people are actively taking part in the discussion in this forum (and every other). Thats not realy a solid base to decide upon.
I know several people who played civ afew times (read: a handfull of games) and said it gets boring after you know what you can do and what happeneds. They wont be posting here because they allready stopped playing.
I know one guy whos very much into the simulation aspect, and hes playing quite regularly. But he will never come to this board because he happeneds to hate forums (which i find quite strange tbh).
And then theres a group of people who dont even own any recent civ, because they have played an older version i found it to be 'just a wargame'. They wont come here because they dont play.
Its like going to a startrek convention and asking if gene Rodenberry was a good Author. The people on this board are here because they like the strategy. But they dont reflect all the potential audience.
